Airplay suddenly not working on WLC2504

[g.ghir]

Hi All,

I have the following setup:

Cisco WLC2504 with 6 APs

Cisco Small Business Switch

We have airplay working with any apple device that could connect to the network on a particular SSID, all of a sudden this has stopped working.  The only change as far as I know is that we originally had 2 Apple TVs hardwired to the network and now we have introduced 3 more but wirelessly.

I have checked and ensured that the following is still correct (as I believe it should be for this to work):

Happy to provide any more information needed, many thanks in advance.

Upgrading will not help. Everything is in the same subnet so you don't need multicast. All that's needed for AirPlay to work is AirTunes. Maybe create a new mDNS profile and apply it to the WLAN. Also maybe reboot the WLC just for kicks.

This was working correctly on v7.4 and suddenly stopped or did you upgrade?

Hi Scott,

I have not upgraded, it was working correctly at 7.4, we are still at 7.4.  We can see the apple devices (ATVs) offering their services on the mDNS page (please see above).  I have connect another wireless vendor (TP-LINK) and can Airplay as I used to be able to on Cisco.

Thanks again,

I don't know what else you can do. AirTunes is the only service that's required for AirPlay to work. If everything is on the same subnet, you don't need multicast for this to work. Just to be clear, your iPads don't see the AppleTV's? This is what you want correct so you can mirror?

Hi Scott,

Correct, iPads do not see AppleTVs.  To add to the problem, when i went to turn on Airtunes the Controller crashed and now is having trouble rebooting.

[Scott Fella]

Well maybe the WLC was the issue. If it does come back up, only enable services you need.

with mdns snooping enabled, it doesn't matter that ap multicast mode is set to multicast/unicast because bonjour multicast is never sent to ap from wlc and we will not see bonjour multicast on wireless also.

when trying to connect on wlc - debug mdns all enable, see what string is missing and add the same to profile.

also, if both device ie., ATV and ipad on same wlan then disable mdns and enable ap mode to unicast.

Hi all,

Sorry I should have commented sooner.  So..........

We got the controller swapped under the RMA and then I went through the configuration bit by bit.  Managed to get it going under the realisation that all the documents that talk about Bonjour Gateway are referring to Layer 3 services.  Turns out that as Scott Fella was saying I don't need much for Airplay to work.  the final config for a flat layer 2 structure is as follows that works for me:
